#!/bin/sh # # This script is intended to be used as a CUPS backend, to create # PDF file on-the-fly. Just create a printer using the device uri # pdf:/path/to/dir/. When printing to this printer, a PDF file # will be generated in the directory specified. The file name will # be either ".pdf" or "unknown.pdf", depending wether the # jobname is empty or not. # # To use it, simply copy this script to your backend directory, and # create a printer with the correct URI. That's it. # # Copyright (C) Michael Goffioul (goffioul@imec.be) 2001 # # This program is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2 of the License, or # (at your option) any later version. # # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
